Hi, the patch attached in JIRA 1580 (submitted by YuNan) is a write barrier implementation for JET that GCv5 is going to use (it doesn't impact anything else). It would be great if some commiter can help to review and commit it. Thanks. -xiaofeng
http://issues.apache.org/jira/browse/HARMONY-1580?page=all The patch is against revision revision 442796. Repeat the desciption of the patch: "Attached patch is an implementation of write barrier for JET compiler of DRLVM. The patch lets JET to call "gc_requires_barriers()" of GC to determine if it needs to insert the write barrier code into the jitted code, so it doesn't impact current DRLVM/GC at all. It calls gc_heap_slot_write_ref( ) of GC module, which takes three parameters. The signature is "void gc_heap_slot_write_ref (Managed_Object_Handle p_obj_holding_ref,Managed_Object_Handle *p_slot, Managed_Object_Handle p_target)". The patch is based on revision 442796. We hope it can be committed to Harmony soon because GCv5 will be depending on it. We don't use existing getaddress__gc_write_barrier_fastcall () in DRLVM because it only remembers object rather than the slot, and the name is not descriptive. But we may use it later. Thanks." --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
